I would skip the bleeding heart tetra, they get quite large and are quite active. I would remove the tetra and get 5 or so male guppies or a single betta.
This is my tank the bleeding heart tetra has been in there for about 3 years now it started out with about 3 others and they all died many fish have gone throughout the years.
